BOZEMAN – A big old Low pressure system stalled just North of the Great Lakes is create a cooler NW flow aloft over Montana for a few days. Most of the moisture with this system well to our east will not impact SW Montana.
A weak disturbance in the NW flow aloft could bring a few showers or isolated thunderstorms Thursday morning into Thursday afternoon.
A similar system is possible Saturday with a few showers and thunderstorms.
